SIGHT-FEED LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 425,590, dated April 15, 1890.

Application tiled July 29, 1889. Serial No. 319,034. (No model.)

`lowing is a specification.

My invention relates to improvements in the construction of sight-feed lubrieators and vention is to simplify the construction of this class of devices and to facilitate the separation and securing together the several parts of the same. This object I attain by the means illustrated in the accompanying' drawings, which are herein referred to and form part of this specification, and in which- Figure l is a front elevation of an upwardlyfeeding lubricator made in accordance with my invention. Fig. 2 is a like elevation of a downwardly-feeding lubricator. Fig. 3 is a vertical section of Fig. 1. Fig. 4 is a plan View of Fig. 1. Fig. 5 is a plan view ot' the upper head detached from the lubricator. Fig. G is a side elevation of the cross-bar or nut and its set-bolt detached from the lubricator. Fig. 7 is a side elevation of the lubricator shown iu Fig.,1; and Fig. 8 is a vertical section of the upper portion of Fig. 7, showing the outlet for the lubricant.

As represented in the drawings, the cage of my lubricator consists of an upper head A, a lower head B, 'side links C, and a cross-bar D, provided with a set-bolt E.

The upper head A is preferably made in the form of an elliptic block, which has in its lower face an annular recess for containing an elastic gasket 1, which forms a cushion tor the upper end of the glass tube F. In the upper face of said upper head is a groove 2, which extends across the major diameter of said head, and preferablyvsaid groove is made wider at its middle than at its ends. From the center of the recess in the lower face of said head there is made an outlet-opening 3, which joins a horizontal branch 4 of said opening for the purpose of affording an outlet for the lubricant which ows upwardly in the tube F. The outlet-openin g 4 passes through a screw-threaded nipple 6, on which the regulating-valve H is secured. In the oppositel ends of said head there are formed vertical grooves 5, which correspond in position with the groove 2, and into which the side bars C are iitted to lie, as shown in Fig. 7, and preferably in such manner that said side bars will iinish iiush with the surface of the head A. An outflow-pipe G, which conveys the lubricant to the vpoint where it is to be applied, is connected to the outlet branch 4 by means of a regulating-valve H.

The lower head B has substantially the same form as the upper head, excepting that the lower head is made without the groove 2 of said upper head, and that the lower head is provided with a conical nipple 7, which contains a central opening 6, that forms a continuation of the inlet-passage 8, through which the lubricant is conducted into the interior of the device. A supply-pipe J, which conveys the lubricant from a reservoir wherein it is contained, is provided with a regulatingvalve l, whereby the iniiow of lubricant into the device can be governed as occasion may require, and said supply-pipe forms a communication with the inlet-passage 8 of the lower head.

The cross-bar D is iitted snugly into the groove 2 in the upper head A and is made to conform to the shape of said groove. The opposite ends ot said cross-bar are each provided with a concaveseat 9, for receiving the hooked upper end of the side links C, which is made to iit into said seat. Said cross-bar is also provided with a centrally-located set-bolt E, which is fitted to bear against the lower side of the groove 2, so that ,when said bolt is screwed inwardly into said cross-bar the latter will be correspondingly raised in said groove.

The side links C are each made to enter into its appropriate groove 5 in the ends of the upper and lower heads, and each is provided with a hook 10 at its upper end, as shown in Fig.,3, and with a hook l1 at its lower end. The hook 10 is made with a convex seat 13, which tits into the concave seat of the crossbar D, so as to engage therein in such manner that the link C can have a swinging movement in respect to said cross-bar, with the convex thereto, and so that a .steam-tight joint will be formedl ateach end ofsaid tube. y

The mode 0f assembling and securing to?- gether the several parts of 'my lubricator is as follows: The cross-bar D, with the set-bolt E- screwed routso that its .peint will `be within the `crossfbar, is inserted in thegreove2. :The

glass tube Fis iixedbetweenxthe heads A and B, so'thatlthe'opposite :ends yof s-aid tubeiwill rest'upou the elastic; gaskets, that arespecially appropriated thereto. 1-ThentheisidenlinkstG are attached im place, first .at `oneend osaid:

heads and -thenf'at .-the 4oppositecindy-and `in" attachiug'fthe last one lof -said'iinkstheseat 13 :is `placed intheconcave seat 9 ofthecrossil bar'D,'while;the lowerend 0f'- thehliukisswungi i outward. The .two :heads are'ioreedll toward;

each otheri untiljthe hook llbf zthepartiallyfu attached] side link will enter the notch Jformedin the lowerheadB/ to receive fit.. Then` by i screwing down the.set-.bolt Ethe headsA and B will be forcedftoward each Lbtherandipress theends of the' tubetfF `into 'the respective' gaskets l, so asA toQfor-m isteamltight joints at those points.

iii

InFig.- 2 `tliedevice -is simply invertedin`- l position, so that the lubricant, instead of rising by reason of its inferiory gravity-as compared with the water always contained in the tube, when the deviceis used in the position shown in Fig. 1 will pass downwardly; but it will be seen that when used in either `position thelsupply-pipe J andfoutiiow-pipe "G maintain their several purposes.

My lubricator does not operate in any manner dierentlyfrom the same kind of lubri cater when constructed in a different manner,

and it should be understood that my inventiondoes not relate toy a newmede 101?Y operation, but is limited to a new construction of lubricators.

What I claim as my invention, and desire :In a' lubricatorfrktheacombination `:of: two heads, each being` providedvwithan elastic ,annulus 1or, gasket andeach being fitted to receiveLsde `links.1for,connectingsaid heads, a tube fixed between saidheadsrwith4 its 'opposite ends bearing on said illgaskets; side links having hooked ends atrbothf extremities, zthe #hooked endsat ione extremityfbeing fitted to engage onA .one ofxsaid headsyand-.the yhooked ends. of: the Aopposite' extremity beingf fitted to engage ,on oppositeeends `ot aflmovable eross4` bal-,and a.icrossbanr` provided with? a=setbolt that-fis fitted to bear againstitheioppositehead, so `as to bind the several parts togetherpas and. forfthe' purpose herein specified.
